means ot a pin 24. The rear ends ot the rods 16 extend within grooves 25 'formed 1n the sides ot the block 22, and are held there by Vstraps 26 or any other suitable means.

The numeral 27 designates a shitting pin, having a reduced serew-tln'eaded end 28, engaging in a screw-threaded opening 2S formed in the forward end ot'the horizontally swinging block 22. This opening er;- tends through the bottom ot the bloclr 22 and is adapted to be brought into registration with a depression 29, 'termed in the tol tace ot the extension 21, ywhen the block 22 is in the normal or central longitudinal position. A ballcatch 30, is carried in the lower end ot the andis .torced downwardly by a spring 31 and is adapted to enter the depression 29.

Rigidly secured to `the opposi te edges oit the overhanging portion 23 ot the support 18, is a pair ot leaf-springs 33, which extend longitudinally of the support in a forwardly direction and hai/'e their tree ends engaging the opposite sides ot a roller-sleeve 34, rotatably mounted upon the pin 27. 1t might be stated at this point that ordinarily, the ball-catch 8O fitting Within the recess 29, will retain the body portion'15 ot the gate in the normal position, n alinement with the swinging support 18. rlhis swinging support turns vertically with the shaft 19. However, should the blow by a traveling vehicle before its tree end is locked against lateralmovement, by means to bev described, such body portion will then be capable ot turning horizontally upon the pivot 24. This will prevent undue injury or destruction otthe gate. [iter the body portion ot the frate is tree trein engagement with the vehicle, the spring or springs 33 will return the body portion of the gate to the normal position, and the ball-catch will enter the depression 29, and vagain loelr the block 22 to the extension 2l.

The numeral 35 designates a snubbing post as a whole embodying an inner stationary vertical channel-iron 36, Figures 1, 2, 3 and 11, which is rigidly attached to the upstanding arm et a generally lil-shaped anchor channel-iron 37, which is preferably embedded in concrete or the like ata peint suitably near the crossing and extendingunder the roadwa This connection is effected by means ot olts 38 or the like. lt is preterred thatj thesebolts be sufficiently strong to withstand all ordinary strains or shocks to which the gate is expected to be subjected, butin the event that the gate should ber subjected to unusual shocks or strains the bolts 3,8 will break thereby releasing the channel-iron 3S. Ot course,the inventionis in no sense restricted to this precise arrangement as the connection may n Arranged upon the outer side of the vertical channel-iron 36 is a shield or housing 39, which is generally U-shaped in horizontal cross section. A block 4() is arranged within this shield and is rigidly secured thereto by any suitable means. fit its lower end, the shield or housing 39 is pivoted to the vertical channel-iron 36 by means ot a transverse pin 41. rlhe shield 39 is provided in its sides, and near its end, .with curved slots 42, concentric with the pin 41, and receiving the ends or" a transverse pin 43, carried by the channel-iron 36. El plurality ot eompressible coil springs 44 are arranged within the upper end ot the shield 39, and are disposed between the block and the channel-iron 8G. 'lhese springs are held in place by trunnions 45 extending into the ends thereof and these trunnions are carried by the channel-iron 3G and block 40. The invention is in no sense restricted to the number or springs shown, as this number may be increased or decreased, depending upon the strength ot the springs or the amount o resistance required.

rlhe U-shaped portion 17 ot the gate is arranged to pass downwardly over the snubbing post 35 limited by contact with a stop 45, Figure 11, which may be in the form ot an angle-iron or the like, rigidly attached to the shield 39 or formed integral therewith. Above this stop, the shield 39 is provided with a recess 47, 'tor the reception of the U-shaped portion 17. T he purpose of this recess is to prevent the gate from slipping upwardly oli ot the snubbing post, when the shield swings inwardly, in the direction longitudinally ot the gate.

The generally U-shaped anchor channeliron 37 has one end attached to the channeliron 36, as explained, while its opposite upstanding end is preferably rigidly attached te the bearing 20, as shown.

lille provide means tor supporting the bod,Y

portion ot the gate against sagging action,

such means including an upstanding trame 48. This trame includes a pair ot upwardly' converging bars 49 see more particularly Figure 9. 'lhese bars are rigidly attached at their lower ends to a vgenerally yl-shaped bar 50, which is arranged upon the forward end et the block 22, projecting downwardly between the rods 16, and bolted to the forward end of the block, as shownat 51.v A. horizontal bar. 52 is rigidly attached to the upper ends ot the bars 49 and is'seeured at its ends to diagonal bars 53, which cross, and extend downwardly and are attached to the ends ot the I bars 49 and the bar 50, as shown at 54. Rigidly attached to the ends ot the bar 52 and the diagonal bars, by riveting, welding or the like, are brace bars 55, which converge rearwardly and are connected a coupling plate 56, which is pivoted upon bolt 5.7, attached to the pin 24. llashers 58 are preferably arranged above and below the coupling plate 56.

The horizontal bar 52 is provided at'its and its downward movement is at their ends with fle vcollars 76, which are `highway crossing. l K ure 11, the U-shaped portion 17 of the gate ends with openings for slidably receiving eyebolts 59, the rear ends of which carry suitably stift` compressible coil springs 60. Attached to the forward ends of these eye-bolts are pairs of diagonal guy Wires 61 and 62. At their upper connected ends, the bars 49 are provided with an opening for slidably receiving an eye-bolt 63, carrying at its rear end a suitably stii compressible coil spring 64. Attached to the forward end of this eye-bolt 63 are longitudinal guy wires 64 and 65.

The numeral 66 designates a cam yoke which is provided with longitudinal openings 67 to receive the side rods 16. This cam yoke is provided upon its rear side with cam faces 68, arranged to engage collars 69, which are adapted to be clamped to the side rods, in adjustment, by bolts 70 or the like. P'ivoted upon the central portion of the cam yoke is a coupling plate 71, having outer openings 72, for connecting with the inner diagonal guy wires 62 and an inner opening 73 for connect-ion with the inner longitudinal wire 64.

The numeral 74 designates a transverse spacing bar, the ends of which are provided with recesses 75, for thereception of the side rods 16. The ends of this spacing bar engage adapted to be clamped in adjustment .to the side rods 16 by means of bolts 77, or the like.. Pivoted or Votherwise connected with thisspacing bar 74, at its center, as shown at 78, is a coupling plate 79, having outer openings S0, for connection with the outer diagonal guy wires 61, and an inner opening 81, for connection with the outer longitudinal guy wire 65. The function of the transverse spacing bar 74 is to afford a connection bet-ween these gu f wires and the side rods 16, and also to retain the side rods suitably spaced, whereby they will properly fit over the snubbing post.

The operation of the apparatus is as follows: Y

lVhen it is desired to prevent an automobile passing over a railway track, the gate is moved to the'lowermost position and is substantially horizontal, as shown in Figures 1 and 2, thereby closing the highway. Ordinarily two gates will be employed at each As clearly shown in Figwill rest upon the stop 46 and be within or adjacent to the recess or depression 47. Should an automobile approaching a railway crossV- ing, when the gate is closed, fail to stop and drive into the central portion of the gate, the gate would then function to arrest the movement of the automobile by increasingly applied resistance to the travel of the automobile. "When the traveling automobile contacts with the side rod 16 of the gate, near the center of the gate, the general action is to flex the gate laterally. This lateral flexing of t-he gate will cause the same to pull upon the snubbing post, causing the shield 59 to swing upon its pivot in a direction parallel with the normal longitudinal axis of the gate. This action, of course, compresses the springs 44 and these springs apply an increasing resistance to the flexing of the gate, which in turn is transmitted to the automobile. lVhen the automobile first engages one side rod 16 the action is to flex this individual rod forwardly, as shown in Figure 4 and the cam saddle 66 is also shifted laterally toward the opposite side rod. This individual flexing of one rod will occur before any perceptible compressing of the springs 44 takes place and affords the initial resistance to the travel of the car. The further travel of the car tends to fiez; both side rods 16 forwardly and this action causes the compression of the springs 44 which provides a further and increasing resistance to the travel of the car. Unless the car should be traveling at an excessive rate of speed, it will be found that the gate will bring t-he car to a stop, wit-hout undue injury to the car or to the gate. Then the car is removed from contact with the gate, the springs 60 and 63 pulling upon the guy wires 61 and 62 tend to shift the cam yoke 66 rearwardly upon the side rods 16. This action of the cam yoke causes the collars 69 to travel' outwardly upon the cam faces 68 and hence the side rods 16 will be returned to the outer or normal positions.

If the gate is partly lowered so that it can be struck by an approaching automobile but is not sufficiently lowered so that ithas proper locking engagement with the snubbing post then when the gate is struck by such automobile it will swing horizontally upon its pivot 24 and permit of the passage of the car, without undue injury, or destruction to the gate. This act-ion would be desirable where the gate is approaching its lowered or raised position but has not sufficiently completed the same to lock the gate in the closed position or to clear the highway. 1V h ile it is preferred to use the yielding snubbing post. in connection with the gate, yet the invention is in no sense restricted to the use of the snubbing post, as under certain conditions the snubbing post may be omitted and the gate used without it.

It is to be understood that the form of our invention, herewith shown and described is to be taken as a preferred example of the sume, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of our invention or the scope of the subjoined claims Hari thus ldescribed our invention, we claim 1.
